Mr Gilani could face jail and loss of office if he is found guilty of contempt

Pakistan's Supreme Court has dismissed an appeal by PM Yousuf Raza Gilani against a contempt of court charge.

Mr Gilani is set to be charged on 13 February with failing to reopen corruption cases against President Asif Ali Zardari.

The prime minister, who appeared before the court last month, faces jail and being barred from office if convicted.

Mr Gilani argues that the president - who denies the corruption charges - has immunity as head of state.

Analysts say the rejection of the appeal will prolong a stand-off between the government and the judiciary, which many believe is being backed by the military as it pursues the case against the civilian administration.
